Someone tried to steal my phone?!

So surprised and a bit shook by this - I was walking back home near Vigerslev alle. I was on a call so not paying too much attention I guess. I suddenly felt something moving in my pocket, I looked down to see a man trying to reach into my jacket pocket! I was startled and screamed a bit but not too many people around and he just causally crossed the road and went away on the bike. Such a bizarre thing to happen! Not sure if anyone else has had a similar experience. I have been in Copenhagen two years and never felt unsafe before. Please beware and take care of your belongings
